No missed data, WRITES as fast as
SRAM, non-volatile, no wear-out,
no lost data during power glitches
An MRAM is fast-write like an SRAM. It is non-volatile like Flash, but does not require page
erase or long write cycles. With an MRAM, event data can be saved at the bus speed and remain saved even through unexpected power loss or power down.
